What lies behind “the internet is slow”?
A problem is usually noticed when a user picks up the phone: the system is slow, files cannot be accessed, the internet keeps dropping. From that point on, finding the cause takes longer than fixing the problem. Yet it is possible to see in advance that a disk is filling up, that a switch port is reporting errors or that a single computer is saturating the line.
Monitoring keeps a constant check on the pulse of your infrastructure. It learns what is normal, turns deviations from normal into alerts and bases your capacity decisions on data through historical reports.
Which solution for which need?
OpManager: device and server health
Monitors routers, switches, firewalls, wireless access points, and physical and virtual servers. It alerts you when a device becomes unreachable or a resource exceeds a threshold. Explore OpManager.
NetFlow Analyzer: traffic and bandwidth
Shows who is using the line, with which application and how much. It spots unusual traffic spikes and lets you make line capacity decisions based on data rather than guesswork. Explore NetFlow Analyzer.
Using them together
The two products belong to the same family and work together: when you see in OpManager that an interface is saturated, you investigate the cause of that traffic in NetFlow Analyzer. For firewall logs, Firewall Analyzer completes this set-up.
Monitoring with Unna
The value of a monitoring system lies not in installing it but in setting up alerts correctly. A system that raises alerts for everything is soon ignored.
- We listen first. Together we identify which systems are business-critical and who needs to be informed in which situation.
- We plan together. We design the devices to be monitored, the threshold values and the alert channels.
- We install and fine-tune. In the first few weeks, we weed out unnecessary alerts and fine-tune thresholds to your actual usage.
- We stay by your side. We follow up on alerts with you and share capacity and performance trends in monthly reports.
Part of the whole
- We spot resource bottlenecks in your virtualisation infrastructure early.
- With server room sensors, we bring environmental conditions into the same monitoring routine.
- We interpret the health and traffic of network security devices alongside monitoring data.
- In our IT consulting and server management services, monitoring is the core tool for periodic maintenance.
Frequently asked questions
Do we need to install agents on our devices?
In most cases, no. Network devices can be monitored without agents via SNMP, Windows servers via WMI, and Linux servers via SNMP or SSH.
Which devices are needed for NetFlow?
A router, switch or firewall that can generate flow data is enough. Most enterprise-grade devices support this feature.
